The values for the function y= cos 4(x-pi) are;
- Amplitude = 1
- Period = π/2
- Horizontal (phase) shift = π
- units Vertical shift = 0 units
<h3>Cosine functions and Properties</h3>
It follows from comparison with the traditional cosine function;
- Amplitude is usually the coefficient of the cos function and hence is, 1 in this case.
- The period, T from the function given is; T =π/2
- The horizontal phase shift is obtained by comparison as; pi.
- Ultimately, the vertical shift is 0 units as there's no y-intercept.

Answer:
Hello!
Explanation:
I understand why you might need help, but please email a teacher about this. You can get in major trouble if you are just to copy and paste. A naritive story is very fun to write! Narrative writing is writing that has a story, characters, conflict, and other essential parts of a story. Narrative writing is often synonymous with a story. And this differs greatly compared to other forms of writing, like in textbooks and certain nonfiction books. So for example, you can rewrite a fairy tale and make it modern! For example, take Snow White, but make it take place in a post-apociliptic world! Or maybe take Cinderella and make it a story about a spy. Hope this helped!
